APPARATUS FOR CARBONATING LIQUIDS SPECIFICATION formingpart of Letters Patent N 0. 71 1,575, dated October 21, 1902. Application filed October 4, 1898. Renewed February 24, 1902. Serial No. 95,230. (No model.)

Be it known that we, PETER E. MALMs'rRoM and OTTO W. AOKERMAN, citizens of the 5 United States, and residents of the city, county,and State ofNew'York, have invented certain new and useful Improvements in Apparatus for Oarbonating Liquids, of which the following is a specification.

Our invention relates to improvements in methods of and apparatus for carbonating liqids, wherein carbonated gas is caused to commingle with liquidsuch, for instance, as water-to produce carbonated water.

In carrying out our invention we provide two cylinders or chambers, one of which is connected with gas and water inlet and also with a cooling-coil, whichcoil communicates through a filter with the other cylinder or chamber, and the latter communicates with a draw-off or outlet for the carbonated liquid. A check-'valve is provided between the firstmentioned cylinder and the coil to prevent back pressure of gas, and a check-valve is provided in the liquid-inlet leading to the first-mentioned cylinder. The gas-inlet is also provided with a suitable cook or valve to control the gas and liquid in the corre sponding cylinder. In carbonating the liquid in our apparatus gas under the desired pressure is let into one cylinder and passes thence through the coil and filter into the other cylinder and also fills the pipes. The gas is then draw ofi from the first-mentioned cylinder and liquid is admitted thereto until it is filled, whereupon gas is again admitted to said cylinder, but under increased pressure, and it thereupon acts to force the liquid from said cylinder through the coil and filter into the other cylinder, whereby the liquid and gas become thoroughly commin- 'gled, and the resulting carbonated liquid can be drawn off for use as desired.

It will be understood that the gas may be supplied from a suitable reservoir and a pressure-regulator interposed between said reservoir and the cylinders.

The invention also consists in the novel details of improvement and the combination of parts, that will be more fully hereinafter set forth, and then pointed out in the claims.

Reference is tobe had to the accompanying drawings, forming part hereof, wherein- Figure l is a side elevation of a carbonating apparatus embodying the invention, the :casing being in section. Fig. 2 is a plan view thereof. Fig. 3 is a side elevation of a cock 'used to control the gas and the liquid. Fig. 4 is a central section thereof. Fig. 5 is a sechorizontal section on the line y y in Fig. 5. Similar numerals of reference indicate cor responding parts in the several views.

1 2 indicate strong cylinders or chambers, which maybe of suitable construction, and '3 is a pipe or tube leading to cylinder 1 to conduct gas thereto from a suitable gas-supply. We have shown a retort or reservoir 4 cylinders, whichretort is connected with pipe 3 by a pipe 3 and other suitable connections, a gas-pressure regulator 5 being interposed in the line ofvpiping in well-known manner, 6 being a stop-cock located in the piping between retort 4 and cylinder 1. v

8 is a pipe that leads to cylinder 1 from a liquid or water supply, such as a street-main, and 9 is a check-valve connected with said pipe to close when pressure is greater in c vlinder 1 than in the liquid-supply and to prevent exit of liquid and gas from cylinder 1. From cylinder 1 extends a pipe 10, that leads to a cooling-coil 11, and said coil leads by a pipe 12 to a filter 13, which latter is in communication with the interior of cylinder or chamber 2. 10 is a check-valve in pipe 10 to prevent back pressure from cylinder 2 to cylinder 1. The filter 13 may be of the construction shown in the application for Letters Patent filed June 1, 1898, Serial No. 682,259, or otherwise. An outlet-pipe 14 extends from cylinder 2 and leads to a suitable draw-off cock 15, whereby the carbonated liquidcan be drawn from the mixing-cylinder 2.

In order to conveniently regulate the pass sage of gas and liquid to and from the cylinder or chamber 1, we have provideda cook or valve 16, that is located between said cylinder and the pressure-regulator 5, being showndisposed between and connecting the pipes 3 and 3. This cook or valve 16 is tion on the line 00 a: of Fig. 4, and Fig. 6 is a for containing carbonated gas to supply the clearly illustrated in Figs. 3, 4, 5, and 6, and it consists, primarily, of acasting having four ways 17 18 19 20, that are controlled by valves. The way 17 extends through the hub 16 to about the width of the casting, where it meets the way 18, that extends at right angles thereto through the hub 16. The way 20 extends parallel to way 18 through hubs 16 and 16 and is joined by way 19, that extends parallel to way 17 through hub 16. The ways 17 and 19 thus have no direct communication. The way 18 and one end of way 20 both open at the end of hub 16 into a chamber 21, that is formed in a sleeve or extension ,22, shown detachably connected with hub 16 by screwthreads. Within chamber 21 is a valve to control ways 18 and 20. For this purpose we have shown a washer or disk 23, resting on a seat 24 at the end of the hub 16 and closing ways 18 and 20, and upon this washer or disk rests a plunger 25, having a stem 26 and shoulder 27. 28 is a spring encircling said stem and bearing against said shoulder, 29 being an adjusting plug or cap having a recess 30 to receive the spring 28 and stem 26, which plug is shown connected with sleeve 22 by screwthreads,whereby it can be adjusted to regulate the tension of spring 28, said plug having a head or thumb piece 31 for its manipulation. The plunger 25 is shown guided in a sleeve 32, located in chamber 21 of sleeve 22. The normal action of spring 28 and plunger 25 is to keep ways 18 and 20 closed. The plunger 25 may be operated to permit the passage of gas from way 18 through chamber 21 to ways 20 and 19 by suitable means. We have shown a lever 33 pivotally connected with casting 16, the inner end of which lever is located in a recess 34 therein and pivoted on a pin or shaft 35, carried by said casting. The end 33 of lever 33 passes through aslot 32 in sleeve 32 and enters a recess 25 in plunger 25, whereby as said lever is operated the plunger can be raised to allow gas to pass from way 18 to way 20.

20 is a bore or recess in hub 16 of casting 16, which communicates with way 20, being substantially a continuation thereof, and said bore is provided with screw-threads that receive corresponding threads on a plug 36, that is provided with a shoulder 37, which bears against the outer end of hub 16. The plug 36 has a longitudinal way or bore 38, that opens into bore 20, and a bore 39, that opens into bore 38, and 40 is a spout connected with bore 39. Into bore 38 extends a pin or rod 41, that is provided with screw-threads which mesh With corresponding threads in bore 38,

I the length of pin 41 being such as to close bore 39 when screwed into bore 38 sufiiciently.

42 is a handle on pin or rod 41 to operate it. Hub 16 is connected with pipe 3 and hub 16 with pipe 3, the arrangement being such that when bore or way 39 is closed and plunger 25 raised gas will pass through ways 17 18 and chamber 21 to ways 20 and 19, and

thus to cylinder or chamber, and when ways 17 and 20 are closed by washer 23 and bore or way 39 opened gas or liquid can pass from cylinder 1 through ways 19, 20, 20, 38, and 39. By preference the cylinders 1 2, coil 11, filter 13, and the connecting-pipes are inclosed within a tank or vessel 43, adapted to receive ice to cool the coil and cylinders, and the parts 9, 15, and 16 may be attached to said vessel, as shown.

The operation of carbonating liquids by means of improvements is as follows: Drawoff cock 15 and way or bore 39 being closed, cock 6is opened and plunger 25 is raised, whereupon gas will pass from pipe 3 under the desired pressure through ways 17 18, chamber 21, ways 20 and 19, and pipe 3 to cylinder or chamber 1, from whence it will pass through pipe 10, coil 11, pipe 12, and filter 13 to cylinder 2. Plunger 25 is next allowed to close ways 18 and 20 and bore 39 is opened, whereupon the gas from cylinder or chamber 1 will escape through pipe 3 and ways 19, 20, 20 38, and 39, check-valve 1O preventing the passage of gas from cylinder 2 and coil 11 to cylinder 1. The gas-pressure in cylinder 1 being thus reduced, liquid will enter cylinder 1 past check-valve 9 through pipe 8, and when the cylinder is filled the liquid will escape through bore or way 39, whereupon the latter will be closed. Cock 6 and valve 25 will again be opened, and gas under increased pressure will enter cylinder 1 and thereupon force the liquid from said cylinder through coil 11 and filter 13 into cylinder or a chamber 2, whereby the liquid will be commingled with the gas in 11 and 2 and become carbonated. The carbonated liquid can then be drawn off through cook 15 as desired.

From the foregoing it will be seen that by the mere manipulation of valve 25 and pin or rod 41 the operation of carbonating liquid is performed, because by merely opening valve 25 and closing bore 39 the cylinders, coil, and pipe will be charged with gas. Then by closing Valve 25 and opening bore 39 one of the cylinders Will be emptied of gas and filled with liquid, and then by again closing bore 39 and opening valve 25 increased gaspressure will cause the liquid to commingle with the gas first charged into the apparatus.

It is evident that the coil 11 can be dispensed with and pipes 10 and 12 connected to join cylinders 1 and 2 direct; also, that the cook 16 can be altered, if desired, but arranged in such manner as to permit the passage of gas to and from cylinder 1, and that other minor details can be changed to suit requirements. We therefore do not limit our invention to the details of construction shown and described, as they may be varied without departing from the spirit thereof.

Having described ourinvention, we claim- 1. The combination of two cylinders, a coil interposed between and connected with said cylinders, a gas-inlet for one cylinder, a cock der, a liquid-inlet therefor, a check-valve to control the supply of liquid to said cylinder, and an outlet for the other'cylinder,-substantially as described.
